Originally, it hard-coded pid file path. It can not be removed when customizing
pid file path.
But rake task can not get pid file path. Therefore, do not remove file in rake
task, makes it possible to judge whether it is restart from the argument of the
command and removes the file in server command.
Fixes#29306
With the exception of what is loaded in active_support/rails,
each file is responsible for its own dependencies. You cannot
rely on runtime order of execution.
- We need to pass the restart command to Puma so that it will use it
while restarting the server.
- Also made sure that all the options passed by user while starting
the server are used in the generated restart command so that they will
be used while restarting the server.
- Besides that we need to remove the server.pid file for the previous running
server because otherwise Rack complains about it's presence.
- We don't care if the server.pid file does not exist. We only want to delete
it if it exists.
- This also requires some changes on Puma side which are being tracked
here - https://github.com/puma/puma/pull/936.
- Fixes#23910.
